Issue D 13

Getting started

Depending on the Development Kit purchased, a Quickstart Manual is provided for Windows CE or embedded Linux to enable users to set up and start using the board. Please read the relevant manual and follow the steps for setting up the board. Once you have completed this task and have a working TITAN system, you can start adding further peripherals, enabling development to begin.

Using the TITAN This section provides a guide to setting up and using of some of the features of the TITAN. For more detailed information on any aspect of the board see Detailed hardware description, page 15.

Using the SDIO socket The TITAN is fitted with a SDIO socket mounted on the top side of the board. The socket is connected to a PXA270 MMC/SD/SDIO controller interface. The TITAN supports hot swap changeover of the cards and notification of card insertion. See the sections SDIO, page 28, and J7 – SDIO socket, page 70, for further details.

Using the serial interfaces (RS232/422/485) The five serial port interfaces on the TITAN are fully 16550 compatible. Connection to the serial ports is made via a 40-way boxed header. The pin assignment of this header has been arranged to enable 9-way IDC D-Sub plugs to be connected directly to the cable. See the sections Serial COMs ports, page 46, and J1 – COMS ports, page 66, for further details.

A suitable cable for COM1 is provided as part of the Development Kit. The D-Sub connector on this cable is compatible with the standard 9-way connector on a desktop computer.

COM4 (RS232) and COM5 (RS422/485) are not available on the standard TITAN-Lite configuration. Eurotech can provide custom configurations (subject to a minimum order quantity) for the TITAN-Lite populated with this feature. Please contact our Sales team to discuss your requirements (see Eurotech Group Worldwide Presence, page 101).

Using the audio features There are four audio interfaces supported on the TITAN: amp out, line out, line in and microphone. The line in, line out and amp interfaces support stereo signals and the microphone provides a mono input. The amplified output is suitable for driving an 8Ω load with a maximum power output of 250mW per channel.

The design supports 520MHz, 416MHz and 312MHz speed variants of the PXA270 processor. The standard variant of the TITAN board includes the 520MHz version of the PXA270. The TITAN-LITE board is fitted with the a 312MHz version of the PXA270. The maximum speed available for extended temperature versions of the TITAN is 416MHz.

A 13MHz external crystal is used to run the PXA270 processor. All other clocks are generated internally in the processor.

The PXA270 processor family provides multimedia performance, low power capabilities and rich peripheral integration. Designed for wireless clients, it incorporates the latest Intel advances in mobile technology over its predecessor, the PXA255 processor. The PXA270 processor features scalability by operating from 104MHz up to 520MHz, providing enough performance for the most demanding control and monitoring applications.

PXA270 is the first Intel® Personal Internet Client Architecture (PCA) processor to include Intel® Wireless MMX™ technology, enabling high performance, low power multimedia acceleration with a general purpose instruction set. Intel® Quick Capture technology provides a flexible and powerful camera interface for capturing digital images and video. Power consumption is also a critical component. Wireless Intel SpeedStep® technology provides the new capabilities in low power operation.

The processor requires a number of power supply rails. All voltage levels are generated on-board from the +5V power input The TITAN uses a specialised power management IC to support Intel SpeedStep® technology.

The PXA270 processor is a low power device and does not require a heat sink for temperatures up to 70°C (85°C for the industrial variant).

Issue D 25

Real time clock The TITAN uses an external real time clock (RTC) (Intersil ISL1208) to store the date and time and provide power management events. The RTC is connected to the I2C bus of the PXA270 processor and is accessible through I2C bus address 0x6F. The RTC is battery backed for the TITAN, but is not battery backed for the TITAN-Lite.

The accuracy of the internal RTC is based on the operation of the 32.768KHz watch crystal. Its calibration tolerance is ±20ppm, which provides an accuracy of +/-1 minute per month when the board is operated at an ambient temperature of +25°C (+77°F). When the board is operated outside this temperature the accuracy may be degraded by -0.035ppm/°C² ±10% typical. The watch crystal’s accuracy will age by ±3ppm max in the first year, then ±1ppm max in the year after, and logarithmically decreasing in subsequent years.

The Intersil ISL1208 RTC provides the following basic functions:

• Real time clock/calendar: - Tracks time in hours, minutes and seconds. - Day of the week, day, month and year.

• Single alarm: - Settable to the second, minute, hour, day of the week, day or month. - Single event or pulse interrupt mode.

• 2 bytes battery-backed user SRAM.

• I2C interface.

PXA270 has an internal real time clock, which doesn’t keep time after hardware reset and should only be used as a wake-up source from deep-sleep.

TITAN user manual

Issue D 26

Watchdog timer The TITAN uses an external watchdog timer (MAX6369), which can be used to protect against erroneous software.

The watchdog timer can be programmed using WD_SET0-2 for timeout periods between 1ms and 60s. When the timeout occurs the TITAN is reset.

The watchdog timeout period is summarized in the following table:

WD_SET2 GPIO 99

WD_SET1 GPIO 97

WD_SET0 GPIO 96 Timeout period

0 0 0 1ms

0 0 1 10ms

0 1 0 30ms

0 1 1 Disabled (default)

1 0 0 100ms

1 0 1 1s

1 1 0 10s

1 1 1 60s

Once the timeout period is set the WD_WDI (GPIO102) watchdog input signal must be toggled within the timeout period. If WD_WDI remains either high or low for the duration of the watchdog timeout period, the watchdog timer triggers a reset pulse.

The watchdog timer clears whenever a reset pulse is asserted or whenever WDI sees a rising or falling edge.

For further details see the Eurotech operating system Technical Manual and the PXA270 Developer’s Manual on the Development Kit CD.


Issue D 27

Memory The TITAN has four types of memory fitted:

• A 16MB (TITAN-LITE only), 32MB or 64MB resident FLASH disk containing:

- Boot loader: Redboot to boot embedded Linux, or Eboot to boot Windows CE. - Embedded Linux or Windows CE. - Application images.

• 64MB or 128MB (64MB for TITAN-LITE) of SDRAM for system memory.

• Static RAM:

- 256KB of SRAM internal to PXA270. - 256KB of SRAM external to PXA270 (battery backed).

• 128 bytes of configuration EEPROM on the I²C bus.

FLASH memory / silicon disk The TITAN supports 16MB (TITAN-LITE only), 32MB or 64MB of AMD Mirrorbit Flash memory for the boot loader, OS and application images. The Flash memory is arranged as 64Mbit x 16-bits (16MB device), 128Mbit x 16-bits (32MB device) or 256Mbit x 16-bits (64MB device) respectively.

The FLASH memory array is divided into equally sized symmetrical blocks that are 64-Kword in size (128KB) sectors. A 128Mbit device contains 128 blocks, a 256Mbit device contains 256 blocks and a 512Mbit device contains 512 blocks.

Whenever the FLASH memory is accessed the FLASH access LED is illuminated.

SDRAM interface There are two standard memory configurations supported by the TITAN: 64MB or 128MB of SDRAM located in bank 0. The 128MB option is not available for the standard TITAN-Lite variants. The SDRAM is configured as 16MB x 32-bits (64MB), or 32MB x 32-bits (128MB) by 2 devices, each with 4 internal banks of 4MB or 8MB x 16-bits.

These are surface mount devices soldered to the board and cannot be upgraded. The size of memory fitted to the board is detected by software to configure the SDRAM controller accordingly.

The SDRAM memory controller is set to run at 104MHz.

TITAN user manual

Issue D 28

Static RAM The PXA270 processor provides 256KB of internal memory-mapped SRAM. The SRAM is divided into four banks, each consisting of 64KB.

The TITAN also has a 256KB SRAM device fitted, arranged as 256Kbit x 8-bits. Access to the device is on 16-bit boundaries; whereby the least significant byte is the SRAM data and the 8-bits of the most significant byte are don’t care bits. The reason for this is that the PXA270 is not designed to interface to 8-bit peripherals. This arrangement is summarized in the following data bus table:

Most significant byte Least significant byte

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Don’t care SRAM data

The SRAM is non-volatile whilst the on-board battery is fitted.

Configuration EEPROM The configuration EEPROM is interfaced directly to the PXA270’s I2C controller. It is a Microchip 24AA01 1Kbit EEPROM organized as one block of 128 x 8-bit memory.

The configuration EEPROM is addressable at I²C serial bus address 0x50 – 0x057 and is accessed in fast-mode operation at 400kbps.

SDIO The SD card socket J7 is interfaced directly to the PXA270’s MMC/SD/SDIO controller.

The MMC/SD/SDIO controller supports multimedia card, secure digital and secure digital I/O communications protocols. The MMC controller supports the MMC system, a low-cost data storage and communications system. The MMC controller in the PXA270 processor is based on the standards outlined in the MultiMediaCard System Specification Version 3.2. The SD controller supports one SD or SDIO card based on the standards outlined in the SD Memory Card Specification Version 1.01 and SDIO Card Specification Version 1.0 (Draft 4).

The MMC/SD/SDIO controller features:

• Data transfer rates up to 19.5Mbps for MMC, 1-bit SD/SDIO and SPI mode data transfers.

• Data transfer rates up to 78Mbps for 4-bit SD/SDIO data transfers.

• Support for all valid MMC and SD/SDIO protocol data-transfer modes.

This is a hot swappable 3.3V interface, controlled by the detection of a falling edge on GPIO 53 (MMC_CD) when an SD card has been inserted, and a rising edge when an SD card is removed.

SD card write protection is connected to the PXA270’s GPIO 52 (MMC_WP), and card detect to GPIO 53 (MMC_CD).

A variety of SDIO cards are available, such as a Camera, Bluetooth®, GPS and 802.11b. More information can be found here: www.sdcard.org/sdio/index.html.

PC/104 interface The TITAN PC/104 interface is emulated from the PXA270 PC card interface to support 8/16-bit ISA bus style signals. As the interface is an emulation, the TITAN does not support some PC/104 features. Please refer to the section Unsupported PC/104 interface features on page 36 for specific details.

Add-on boards can be stacked via the PC/104 interface to enhance the functionality of the TITAN. Eurotech has an extensive range of PC/104 compliant modules and these can be used to quickly add digital I/O, analogue I/O, serial ports, video capture devices, PC card interfaces, etc.

The ISA bus is based on the x86 architecture and is not normally associated with RISC processors. You would need to modify the standard drivers to support any third party PC/104 modules.

Any PC/104 add-on board attached to the TITAN is accessible from the PC card memory space socket 1. The memory map is shown in the following table:

Address Region size Region name

0x30000000 – 0x300003FF 1KB PC/104 I/O space, 8/16-bit

0x30000400 – 0x3BFFFFFF - Reserved

0x3C000000 – 0x3C1FFFFF 16MB PC/104 memory space, 16-bit (or 8-bit write only)

0x3C200000 – 0x3FFFFFFF - Reserved

PC/104 interface details The PC/104 bus signals are compatible with the ISA bus electrical timing definitions.

All signals between the PXA270 and the PC/104 are buffered. When the PC/104 bus is not in use, all output signals with the exception of the clock signals are set to their inactive state.

The TITAN provides +5V (VCC_PER) to the PC/104 connectors J13 and J14. If a PC/104 add-on board requires a +12V supply, then +12V can be supplied via the TITAN power connector J15 pin 4. If -12V or -5V are required, these must be supplied directly to the PC/104 add-on board.

Do NOT attempt to power the TITAN using the VCC_PER pins! VCC_PER is an isolated +5V supply switched under hardware control from the VCC input on J15 pin 1. ALWAYS provide +5V to VCC on J15 pin 1.

If J15 pin 4 is used to supply +12V to the PC/104 connector J13 pin B4. Do NOT exceed 700mA supply current at 70°C ambient, or 600mA at 85°C ambient.

PC/104 interrupts The PC/104 interrupts are combined together in the TITAN hardware. When an interrupt is received on the PC/104 interface, the hardware generates an interrupt on pin GPIO 17 (active high) of the PXA270 processor.

The PC/104 interrupting source can be identified by reading the PC104_IRQ registers I1_REG and I2_REG located at addresses 0x12800000 and 0x01800000 respectively. The registers indicate the status of the interrupt lines at the time the register is read. The relevant interrupt has its corresponding bit set to ‘1’. The PXA270 is not designed to interface to 8-bit peripherals, so only the least significant byte from the word contains the data.

PC/104 IRQ9, IRQ14 and IRQ15 are not available under Windows CE as all interrupt sources are fully utilised.

Once the PXA270 microprocessor has serviced a PC/104 interrupt, the corresponding add-on-board clears the interrupt by driving the IRQ signal low. When the TITAN hardware sees the interrupt go low the corresponding bit is automatically cleared from the I1_REG or I2_REG register.

If no further interrupts are pending the TITAN hardware drives GPIO 17 low once the interrupt has been cleared at the source.

TL


Issue D 35

In cases where other PC/104 IRQs are asserted while the driver is processing a PC/104 IRQ, the TITAN drives GPIO 17 low for 375ns to 500ns once this interrupt has been cleared. This short low pulse indicates to the PXA270 that there is another pending interrupt. This situation is shown in the following diagram:

PC/104 reset The reset generated to the PC/104 add-on board is a combination of the nRESET_OUT# pin of the PXA270 and the status of the PC104_RST bit of the control register C_REG.

To reset PC/104 add-on boards independently from the global TITAN board reset, set the PC104_RST bit to ’1’ in the C_REG register located at the address 0x13000000. To clear the PC/104 reset, write a ‘0’ to the PC104_RST bit.

Unsupported PC/104 interface features The TITAN does not support the following PC/104 bus features:

• DMA is not supported. Therefore, AEN signal is set to a constant logical zero.

• Bus mastering is not supported. Therefore, do not connect any other master add-on board to the TITAN PC/104 interface.

• Shared interrupts are not supported. Therefore, do not connect more than one add-on board to the same interrupt signal line.

• BALE signal is set to a constant logical one as the address is valid over the entire bus cycle. Only add-on PC/104 boards that implement transparent latch on address lines LA17-LA23 are compatible with the TITAN implementation of BALE.

• The PXA270 PCMCIA memory controller does not support 8-bit memory read accesses for common memory space.

• The PXA270 PCMCIA memory controller does not support PC/104 MEMCS# signal, so there is no support for dynamic bus sizing.

Flat panel display support The PXA270 processor contains an integrated LCD display controller. It is capable of supporting both colour and monochrome single- and dual-scan display modules. It supports active (TFT) and passive (STN) LCD displays up to 800x600 pixels.

The PXA270 can drive displays with a resolution up to 800x600, but as the PXA270 has a unified memory structure, the bandwidth to the application decreases significantly. If the application makes significant use of memory, such as when video is on screen, you may also experience FIFO under-runs causing the frame rates to drop or display image disruption. Reducing the frame rate to the slowest speed possible gives the maximum bandwidth to the application. The display quality for an 800x600 resolution LCD is dependant on the compromises that can be made between the LCD refresh rate and the application. The PXA270 is optimized for a 640x480 display resolution.

A full explanation of the graphics controller operation can be found in the Intel PXA27x Processor Family Developer’s Manual included on the support CD.

The flat panel data and control signals are routed to J4. See the section J4 – LCD connector, page 68, for pin assignment and part number details.

The ZEUS-FPIF interface board allows the user to easily wire up a panel using pin and crimp style connectors (see page 88). Contact Eurotech (see Eurotech Group Worldwide Presence, page 101) for purchasing information for the ZEUS-FPIF. Alternatively, the display interface is connected to an LVDS interface (see the section LVDS interface, page 41). The LVDS interface provides useful when displays need to be located more than 300mm (12") from the TITAN.

The following tables provide a cross-reference between the flat panel data signals and their function, when configured for different displays.

TFT panel data bit mapping to the TITAN

The PXA270 can directly interface to 18-bit displays, but from a performance point of view it is better to use 16-bits only. 18-bit operation requires twice the bandwidth of 16-bit operation.

LCD logic and backlight power The display signals are +3.3V compatible. The TITAN contains power control circuitry for the flat panel logic supply and backlight supply. The flat panel logic is supplied with a switched +3.3V (default) or +5V supply (see the section LCD supply voltage jumper – LK2 on JP2, page 79, for details). The backlight is supplied with a switched +5V supply for the inverter.

There is no on-board protection for these switched supplies! Care must be taken during power up/down to ensure the panel is not damaged due to the input signals being incorrectly configured.

The PXA270 GPIO 101 pin controls the supply voltage for the LCD display.

LCDEN (GPIO 101) Selected LCD function

0 LCDSAFE power off (default)

1 LCDSAFE 3.3V/5V power on

The LCD supply may be changed to 5V by moving the jumper position of JP2, see section LCD supply voltage jumper – LK2 on JP2, page 79, for details. If the flat panel logic is powered from 5V, it must be compatible with 3.3V signalling, please check the LCD panel datasheet for details.

The PXA270 GPIO 19 pin (BKLEN signal) controls the supply voltage for the backlight inverter.

BKLEN (GPIO 19) Selected backlight function

0 BKLSAFE power off (default)

1 BKLSAFE 5V power on

The BLKEN signal is routed (un-buffered) to connector J4. See the section J4 – LCD connector, page 68, for J4 pin assignment and connector details.

If you want to use a 12V backlight inverter, then the switched 5V supply on BLKSAFE or the control signal BLKEN can be used to control an external 12V supply to the inverter.

Typically the following power up sequence is as follows (please check the datasheet for the particular panel in use):

1 Enable display VCC.

2 Enable flat panel interface.

3 Enable backlight.

Power down is in reverse order.

LCD backlight brightness control GPIO 16 of the PXA270 processor is used for backlight brightness control (signal PWM0 on J4 connector). The control of the backlight brightness is dependant upon the type of backlight inverter used in the display. Some inverters have a ‘DIM’ function, which uses a logic level to choose between two levels of intensity. If this is the case then GPIO 16 (alternative function 0) is used to set this. Other inverters have an input suitable for a pulse-width modulated signal or analogue voltage control. In this case GPIO 16 should be configured as PWM0 (alternative function 2).

When a PWM signal is required the PWM0 signal must be passed through a low pass filter. The ZEUS-FPIF board provides a low pass filter for this function (see page 88). Contact Eurotech (see Eurotech Group Worldwide Presence, page 101) for purchasing information for the ZEUS-FPIF.

STN BIAS voltage The TITAN can provide a negative and a positive bias voltage for STN type displays. The negative and positive bias voltages are set to -22V and +22V respectively. Pin connections for these can be found in section J4 – LCD connector, page 68.

BIAS_EN (GPIO 82) Selected backlight function

0 NEGBIAS & POSBIAS power off (default)

1 NEGBIAS & POSBIAS power on

Please contact Eurotech for details of other bias voltages. Contact details are provided in Eurotech Group Worldwide Presence, page 101.

LVDS interface There is an optional Low-Voltage Differential Signalling (LVDS) interface available on the TITAN. LVDS combines high data rates with low power consumption. The benefits of LVDS include low-voltage power supply compatibility, low noise generation, high noise rejection and robust transmission signals.

The National Semiconductor transmitter DS90C363 is used to convert 16 bits of LCD data signals into three LVDS data streams. A phase-locked transmit clock is transmitted in parallel with the data streams over a fourth LVDS link. The LVDS signals are routed to the connector J8. For connector details see the section J8 – LVDS connector, page 71.

The LVDS transmitter is enabled using the signal LVDS_EN (GPIO 21). Details are shown in the following table:

LVDS_EN (GPIO 21) Selected LVDS function

0 LVDS power down (default)

1 LVDS enable

The LVDS transmitter can be programmed for rising edge strobe or falling edge strobe operation through a signal LVDS_FES# (GPIO 27). This is shown below:

LVDS_FES# (GPIO 27) Selected LVDS function

0 Falling edge strobe

1 Rising edge strobe (default)

If the FPIF-LVDS-TX is to be connected directly to an LVDS display via the Hirose connector J2, then this link selects the displays LVDS Receiver input map. Fitting or not fitting a jumper to JP3 sets J2 pin 20 (MSL) to 3.3V or GND (default) respectively.

When the LVDS interface is used, connector LK3 on JP3 should be set to the correct setting for the display. See section LVDS mode select [MSL] jumper – LK3 on JP3, page 79, for details. Please consult the manual of your LVDS display for which setting to use for the National Semiconductor DS90C383 LVDS Transceiver.

Connector J4 should be used to supply the power and brightness control for the backlight inverter when the LVDS interface is used. See the section J4 – LCD connector, page 68, for J4 pin assignment and connector details.

USB

USB host There are two USB host interfaces on the TITAN. These comply with the Universal Serial Bus Specification Rev. 1.1, supporting data transfer at full-speed (12Mbps) and low-speed (1.5Mbps).

There are four signal lines associated with each USB channel: VBUS, DATA+, DATA and GND. Their arrangement is summarized in the illustration below:

A USB power control switch controls the power and protects against short-circuit conditions.

If the USB voltage is short-circuited, or more than 500mA is drawn from either supply, the switch turns the power supply off and automatically protects the device and board. If an over current condition occurs on a USB channel, the over current condition is flagged to GPIO 88 and GPIO 114 for USB channel 1 and channel 2 respectively. This is shown in the following tables:

More information about the USB bus and the availability of particular USB peripherals can be found at www.usb.org.

USB client The TITAN USB host port 2 can be configured under software to be a client.

The following diagram shows the connection between PL17 and a USB type A connector:

Do NOT attempt to power the TITAN using the VBUS 1 or VBUS 2 pins! VBUS 1 and VBUS 2 are isolated +5V supplies switched under hardware control from VCC_PER.

ALWAYS use the USB client cable provided with the development kit. This cable does not provide power down the cable and avoids reverse powering the TITAN from a USB host when the TITAN has no power on the VCC input on J15 pin 1. Reverse powering the TITAN from the VBUSn pins can make the TITAN operate erratically and may cause serious damage to the TITAN.

Ethernet The TITAN SBC provides a single 10/100-BaseTX interface with MAC and complies with both the IEEE802.3u 10/100-BaseTX and the IEEE 802.3x full-duplex flow control specifications.

A single Davicom DM9000A Ethernet controller is used to implement the Ethernet interface on the TITAN. The DM9000A device provides an embedded PHY and MAC and connects to the 10/100-BaseTX magnetics. The DM9000A also supports the AUTO-MDIX feature. Configuration data and MAC information are stored in an external serial EEPROM (93LC46).

The DM9000A device is connected to the PXA270 data bus (16-bit), and is memory mapped. Connection to the TITAN Ethernet port is via header J11. See J11 – 10/100BaseTX Ethernet connector, page 72, for pin assignment and connector details.

A second header J12 provides the speed and link status LED signals. See J12 – Ethernet status LEDs connector, page 73, for pin assignment and connector details. The output lines sink current when switched on, therefore the anode of each LED should be connected to pins 1 and 3 of J12 and the cathode to the appropriate status line.

The link LED illuminates when a 10 or 100base-T link is made, and the speed LED illuminates when 100Mbps speed is selected.

The Ethernet Breakout interface board provides the user with an RJ45 connector with LEDs to connect an Ethernet cable to the TITAN (see page 96). Contact Eurotech (see Eurotech Group Worldwide Presence, page 101) for purchasing information for the Ethernet Breakout.

COM1 – RS232 interface Uses the Full Function UART in the PXA270 (FFUART). The port is buffered to RS232 levels with ±15kV ESD protection, and supports full handshaking and modem control signals. The maximum baud rate on this channel is 921.6kbps.

A factory fit option configures COM1 as TTL Level signals to interface to a modem. Please contact Eurotech for details. Contact details are provided in Eurotech Group Worldwide Presence, page 101.

COM4 – RS232 interface The COM4 RS232 interface is supported on channel 0 of an Exar XR16C2850 with 128 bytes of Tx and Rx FIFOs, and buffered to RS232 levels with ±15kV ESD protection. The maximum baud rate on this channel is 921.6kbps.

COM5 – RS422/485 interface The COM5 RS422/485 interface is supported on channel 1 of an Exar XR16C2850 with 128 bytes of Tx and Rx FIFOs, and buffered to RS422/485 levels with ±15kV ESD protection. The maximum baud rate on this channel is 921.6kbps.

Two GPIOs from the PXA270 provide RS422/RS485 selection and termination resistor selection options. The two control signals are SEL_485# on GPIO 81 and SEL_TERM on GPIO 115. This is shown in the following table:

SEL_485# (GPIO 81) Selected COM5 function 0 RS485 half duplex

1 RS422 full duplex [default]

SEL_RS485# is at logic ‘1’ upon reset.

The control signal SEL_TERM is used to enable/disable the RS422/485 line termination and must be enabled if the TITAN board is at the end of the network. This is shown in the following table:

SEL_TERM (GPIO 115) COM5 termination resistors (120Ω) 0 Disconnected

SEL_TERM is at logic ‘1’ upon reset.

The RS485/422 driver (LTC2859) on the TITAN features a logic-selectable reduced slew mode, which softens the driver output edges to control the high frequency EMI emissions from equipment and data cables. The reduced slew rate mode is entered by taking the SLO# pin low, where the data rate is limited to about 250kbps. Slew limiting also mitigates the adverse effects of imperfect transmission line termination caused by stubs or mismatched cables. The following table illustrates the selectable slew rates:

RS422 The RS422 interface provides full-duplex communication. The signals available are TXA, TXB, RXA, RXB and Ground. The maximum cable length for an RS422 system is 4000ft (1200m) and supports 1 transmitter and up to 10 receivers.

RS485 This is a half-duplex interface that provides combined TX and RX signals. On J1, pin 5 provides TXB/RXB and pin 6 provides TXA/RXA. A ground connection is also required for this interface. The maximum cable length for this interface is the same as for RS422 (4000ft), but RS485 supports up to 32 transmitters and receivers on a single network. Only one transmitter should be switched on at a time.

The TITAN uses the RTS signal to control transmission. When this signal is at logic ‘1’ the driver is switched off and data can be received from other devices. When the RTS line is at logic ‘0’ the driver is on. Any data that is transmitted from the TITAN is automatically echoed back to the receiver. This enables the serial communications software to detect that all data has been sent, and disable the transmitter when required. The UART used on the TITAN for COM5 has extended features including auto-RTS control for RS485. This forces the RTS signal to change state (and therefore the direction of the RS485 transceivers) when the last bit of a character has been sent onto the wire. Please refer to the XR16C2850 datasheet on the Development Kit CD for more information.

The RS422/485 cable shield MUST be connected between TITAN J1 pin 9 (GND) and the ground connection of the connecting equipment. Failure to do so can result in TITAN RS422/485 transceiver being permanently damaged.

I²C The PXA270 I²C interface is brought out to the COMs connector J1. See the section J1 – COMS ports, page 66, for connection details.

The I²C bus is also used with the Quick Capture interface. See the section Quick Capture camera interface, page 51, for more information.

The following table lists the on-board I²C devices:

Device name I²C address

External GPIO (MAX7313) 0x20

Temperature sensor (LM75A) 0x48

RTC (ISL1208) 0x6F

Config PROM (24AA01) 0x50-0x57

The I²C unit supports a fast mode operation of 400kbps and a standard mode of 100kbps.

Fast mode devices are downward compatible and can communicate with standard mode devices in a 0 to 100kbps I²C bus system. However, standard mode devices are not upward compatible, so they should not be incorporated in a fast mode I²C bus system as they cannot follow the higher transfer rate and unpredictable states would occur.

The I²C unit does not support the hardware general call, 10-bit addressing, high-speed mode (3.4Mbps) or CBUS compatibility.

You must keep bus loads added by the Quick Capture camera, and any other devices added to the serial communications connector, below 140pF.

Ensure any other devices added to the I²C interface do not have the same addresses as detailed in the table above.


Issue D 51

Quick Capture camera interface The Quick Capture interface is a component of Intel® Quick Capture technology which provides a connection between the PXA270 processor and a camera image sensor. The Quick Capture interface is designed to work primarily with CMOS-type image sensors and supports resolutions up to 4 mega pixels. However, it may be possible to connect some CCD-type image sensors to the PXA27x processor, depending on the specific CCD sensor’s interface requirements.

The Quick Capture interface acquires data and control signals from the image sensor and performs the appropriate data formatting prior to routing the data to memory using direct memory access (DMA). A broad range of interface and signalling options provides direct connection. The image sensor can provide raw data through a variety of parallel and serial formats. For sensors that provide pre-processing capabilities, the Quick Capture interface supports several formats for RGB and YCbCr colour space.

The Quick Capture interface signals are connected to the header J2. An I2C interface is available on the same header since most of the camera image sensors require an I2C control interface. For connector details see the section J2 – Camera interface connector, page 67.

General purpose I/O A Maxim MAX7313 I²C I/O expander provides sixteen general purpose input/output lines on header J3. Each I/O port can be individually configured as either an open-drain current-sinking output rated at 50mA with a 10K pull-up to +5V (VCC_PER), or a logic input with transition detection. The MAX7313 supports hot insertion and all inputs are +5V tolerant.

The MAX7313 can configure outputs for PWM current drive. The MAX7313 includes an internal oscillator, nominally 32kHz, to generate PWM timing for LED intensity control. PWM intensity control can be enabled on an output-by-output basis, allowing the MAX7313 to provide any mix of PWM LED drives and glitch-free logic outputs. PWM can be disabled entirely, in which case all output ports are static and the MAX7313 operating current is the lowest because the internal oscillator is turned off.

The I/O Expander is addressable at I²C serial bus address 0x20 and is accessed in fast-mode operation at 400kbps. On power-up all control registers are reset and the MAX7313 enters standby mode. Power-up status makes all ports into inputs, so the state of all 17 ports (P0-P16) is logic high (through 10K pull-up to 5V).

See the section J3 – GPIO connector, page 67, for connector pinout and mating connector details. The signals on J3 correspond to the pin names of the MAX7313 (P0-P15).

Port 16 of the MAX7313 is configured as an interrupt, so that any I/O Expander GPIO pin configured as an input can cause the PXA270 to be interrupted on GPIO116. These can also be used as PXA270 wake-up sources from sleep mode.

Temperature sensor There is a Philips LM75A temperature sensor on the TITAN. The LM75A is a temperature-to-digital converter using an on-chip band-gap temperature sensor and Sigma-delta A-to-D conversion technique. The device is also a thermal detector providing an over-temperature detection output (OVERTEMP signal on GPIO 12), which can be used to wake the PXA270 up from sleep. The accuracy of LM75A is ±2oC (at -25oC to 1000C), and ±3oC (at -55oC to 1250C). The LM75A is connected to the I2C bus of the PXA270 processor, and is accessible at I2C bus address 0x48.

The TITAN shall be reset if the supplies fall below the thresholds shown in the table.

VCC_CORE, VCC_PLL and VCC_SRAM rails are controlled by the PXA270 hardware control signal PWR_EN. They are switched off when PXA270 is in sleep or deep-sleep mode.

VCC_PER, +3V3 and +2V8_CIF supply rails are controlled by the PXA270 hardware control signal SYS_EN. They are switched off when PXA270 is in deep-sleep mode.

VBUS 1 and VBUS 2 are controlled by the PXA270 software controlled signals USB_PWE1 and USB_PWE2 respectively. They are switched off on power-on, reset, sleep or deep-sleep.


Issue D 55

LCD_SAFE and BKLSAFE are controlled by the PXA270 software controlled signals LCDEN and BKLEN respectively. They are switched off on power-on, reset, sleep or deep-sleep.

Do NOT attempt to power the TITAN using the VCC_PER, VBUS 1 or VBUS 2 pins!

VCC_PER is an isolated +5V supply switched under hardware control from the VCC input on J15 pin 1. ALWAYS provide +5V to VCC on J15 pin 1.

VBUS 1 and VBUS 2 are isolated +5V supplies switched under hardware control from VCC_PER.

If J15 pin 4 is used to supply +12V to the PC/104 connector J13 pin B4. Do NOT exceed 700mA supply current at 70°C (158°F) ambient, or 600mA at 85°C (185°F) ambient.

If an LCD display is used, ensure the total current requirement on 3.3V does not exceed 1.4A! Please check the datasheets of the devices you are using, as this supply is not protected!

Power management IC The Linear Technology LTC3445 is used to provide the power supply for PXA270. It is specifically designed for the PXA27x family of microprocessors.

The LTC3445 contains a high efficiency buck regulator (VCC_CORE), two LDO regulators (VCC_PLL, VCC_SRAM), a PowerPath controller and an I2C interface. The buck regulator has a 6-bit programmable output range of 0.85V to 1.55V. The buck regulator uses either a constant frequency of 1.5MHz, or a spread spectrum switching frequency. Using the spread spectrum option (default set to 22.4%) gives a lower noise regulated output, as well as low noise at the input. In addition, the regulated output voltage slew rate is programmable via the Power Management I2C interface of the PXA270.

Battery backup An on-board non-rechargeable battery (CR2032) provides battery backup supply for the ISL1208 RTC and SRAM. An external battery (CR2032 or similar) may also be fitted. To use an external battery see the section J15 – Power connector, page 75, for connection details.

The table below shows the typical and maximum current load on the external battery:

Device load on battery Typical (µA) Maximum (µA)

On-board SRAM 0.5 3

ISL1208 RTC with clock out off 0.4 0.95

Supply supervisor 0.5 0.5

Total 1.4 4.45

Based on the worst-case figures of 4.45µA current consumption, a 220mAh CR2032 battery cell will backup the TITAN (whilst in continuous deep sleep) for > 5 years.

The TITAN does not provide a battery charging circuit.

If the TITAN is to be used at operating temperature extremes, please be aware that if the battery cell is fitted they are typically rated at -30˚C to +60˚C.

Processor power management First available in the PXA270 processor, wireless Intel SpeedStep® technology dynamically adjusts the power and performance of the processor based on CPU demand. This can result in a significant decrease in power consumption.

In addition to the capabilities of Intel Dynamic Voltage Management, the Intel XScale micro architecture of the PXA27x family incorporates three new low power states. These are deep idle, standby and deep sleep. It is possible to change both voltage and frequency on the fly by intelligently switching the processor into the various low power modes. This saves additional power while still providing the necessary performance to run rich applications.

Wireless Intel SpeedStep® technology includes the following features:

• Five reset sources: power on, hardware, watchdog, GPIO and exit from sleep and deep sleep modes (sleep exit).

• Multiple clock speed controls to adjust frequency, including frequency change, turbo mode, half-turbo mode, fast-bus mode, memory clock, 13M mode, A-bit mode and AC ’97.

• Switchable clock source.

• Functional unit clock gating.

• Programmable frequency change capability.

• One normal operation power mode (run mode) and five low power modes to control power consumption (idle, deep idle, standby, sleep and deep sleep modes).

• Programmable I2C-based external regulator interface to support changing dynamic core voltage, frequency change and power mode coupling.

PXA270 power consumption depends on the operating voltage and frequency, peripherals enabled, external switching activity and external loading and other factors. The tables below contain the power consumption information at room temperature for several operating modes: active, idle and low power modes. For active power consumption data, no PXA270 peripherals are enabled except for UART.

Wake-up sources The PXA270 offers two sleep modes:

• Sleep mode offers lower power consumption by switching off most internal units. There is no activity inside the processor, except for the units programmed to retain their state in the PSLR register, the real time clock and the clocks and power manager. Because internal activity has stopped, recovery from sleep mode must occur through an external or internal real time clock event. External wake-up sources are GPIO<n> edge detects (they are listed in the section PXA270 GPIO pin assignments, page 19).

• Deep-sleep mode offers the lowest power consumption by powering most units off. There is no activity inside the processor, except for the real time clock (RTC) and the clocks and power manager. Because internal activity has stopped, recovery from deep-sleep mode must be through an external event or an RTC event. In deep-sleep mode, all the PXA270 power supplies (VCC_CORE, VCC_SRAM, VCC_PLL, VCC_IO excluding VCC_BATT) are powered off for minimized power consumption. On the TITAN, the main +3.3V rail supplies the VCC_IO power domain of the PXA270. Since the +3.3V supply is switched off in deep-sleep mode, all the on-board peripherals are powered off and it is not possible to use external wake-up sources. In this situation, recovery from deep-sleep mode must be through an internal RTC event.

For more information on PXA270 power management, see section 3.6 in the Intel PXA27x Processor Family Developer’s Manual, included on the Development Kit CD.

COMs power management GPIO 20 on the PXA270 can be used to power down the RS232 transceivers on COM1, 2, 3 and 4. The following table shows the effect of GPIO 20 on the RS232 transceivers:

RS232_SHDN# (GPIO 20) Operation status Transmitters Receivers

0 Normal operation Active Active

1 Shutdown High-Z High-Z

Shut can reduce the consumption of the RS232 transceivers down to near zero (3μW).

COM4 and COM5 are generated from an external Exar XR16C2850 DUART. This device supports a sleep mode with an auto wake up. By enabling this feature the DUART enters sleep mode when there are no interrupts pending. The device resumes normal operation when any of the following occur:

• Receive data start bit.

• Change of state on: CTS, DSR, CD, RI.

• Data is being loaded into transmit FIFO.

If the device is awoke by one of the above conditions, it returns to the sleep mode automatically after the condition has cleared. In sleep mode the XR16C2850 consumes 0.1mW. Please see the XR16C2850 datasheet on the Development Kit CD for information on enabling the sleep mode.

GPIO115 on the PXA270 is used to connect or disconnect the 120Ω termination resistors on COM5.

Ethernet power management The Ethernet controller (Davicom DM9000A) incorporates a number of features to maintain the lowest power possible.

The device can be put into a power-reduced mode by setting the PHY control register bit 16.4. In power-reduced mode, the device transmits the fast link pulses with minimum power consumption. It also monitors the media for the presence of a valid signal and, if detected, the device automatically wakes up and resumes normal operation. The power consumption in power-reduced mode (without cable) is 31mA, 102.3mW.

The PHY can be put into a sleep mode by setting the PHY control register bit 16.1, which powers down all the circuits except the oscillator and clock generator circuit.

The PHY can be put into a power-down mode by setting the PHY control register bit 0.11 which disables all transmit and receive functions but not the access to PHY registers. The power consumption in power-down mode is 21mA, 69.3mW.

The lowest power consumption is achieved when the system clock is turned off by setting bit 0 in the SCCR register to reduce power consumption down to 7mA, 23.1mW.

For more information about power management, refer to the DM9000A datasheet on the Development Kit CD.

USB power management A USB power control switch controls the power and protects against short-circuit and over-current conditions on USB host ports.

If the USB voltage VBUSx is short-circuited, or more than 500mA is drawn from any VBUSx supply, the switch turns off the power supply and protects the device and board automatically. The VBUSx power supplies are derived from the TITAN +5V supply.

The following table shows the PXA270 assignments for power enable and over-current signals:

GPIO Host 1/2 functions Active

GPIO 89 USB_PWE1 High

GPIO 88 USB_OC1#

GPIO 22 USB_PWE2 High

Audio power management The audio CODEC Wolfson WM9712L supports the standard power down control register defined by AC’97 standard (26h). In addition, the individual sections of the chip can be powered down through register 24h. Significant power savings can be achieved by disabling parts of WM9712L that are not used.

Shutting down all the clocks and digital and analogue sections can reduce WM9712L consumption down to near zero (1.65μW).

For more information about power management, refer to the WM9712L datasheet contained on the Development Kit CD.

LVDS power management If the LVDS transmitter is not required it can be placed in power down mode by applying a high level to the PXA270 GPIO 21 LVDS_EN signal. The power consumption in power down mode is 180μW. This is shown in the following table:

LVDS_EN (GPIO 21) LVDS operation status

0 LVDS power down (default)

1 LVDS enable

Clock generator power management Two clock synthesizer ICs (Cypress CY22381) can be placed in low power mode by shutting down the clock outputs when the corresponding interfaces are not used. To put these into low power mode, apply a low level to GPIO 18 pin on the PXA270 (signal CLK_SHDN#).

CLK_SHDN# (GPIO 18) Clock operation status

0 Shutdown clocks

1 Clocks running

Once shutdown the following clocks are affected:

• 8MHz and 14.318MHz PC/104 clocks.

• 14.7456MHz DUART clock.

• 24.576MHz audio clock.

• 25MHz Ethernet PHY clock.

This reduces the power consumption of the clock generators down to 33μW.

Temperature sensor power management The LM75A device can be set to operate in two modes: normal or shut down. In normal operation mode, the temp-to-digital conversion is executed every 100ms and the Temp register is updated at the end of each conversion. In shut down mode, the device becomes idle, data conversion is disabled and the Temp register holds the latest result; however, the device I2C interface is still active and register write/read operation can be performed. The device operation mode is controllable by programming bit B0 of the configuration register. The temperature conversion is initiated when the device is powered-up or put back into normal mode from shut-down. The power consumption in shut-down mode is near zero (11.5μW).

For more information about power management, refer to the LM75A datasheet contained on the Development Kit CD.

I/O expander power management When the serial I2C interface is idle and the PWM intensity control is unused, the MAX7313 automatically enters standby mode. If the PWM intensity control is used, the operating current is slightly higher because the internal PWM oscillator is running. The power consumption in standby mode (with PWM disabled) is near zero (3.6μW).

The IO expander has 10kΩ pull-up resistors on P0-15. Dependant on which of these signals are configured as input or output, or what logic level each output is configured at during sleep determines the current attributed by these resistors during sleep.

P0-15 direction Current / Watts each Current / Watts all

Input (floating) 0mA / 0mW 0mA / 0mW

Input high (VCC_PER) 0mA / 0mW 0mA / 0mW

Input high (3.3V) 0.17mA / 0.29mW 2.72mA / 4.62mW

Input low (0V) 0.5mA / 2.5mW 8mA / 40mW

Output logic level low (no further pull-ups at termination)

0.5mA / 2.5mW 8mA / 40mW

Output logic level high (loaded and no further pull-ups at termination)

0.5mA / 2.5mW (max) 8mA / 40mW (max)

Output logic level high (no load) 0mA / 0mW 0mA / 0mW

Set up the IO expander P0-15 signals accordingly to your application to achieve the optimum power savings during sleep.

If none of the IO expander P0-15 signals are used set them all to be inputs.

Configuration PROM power management When the serial I2C interface is idle the 24AA01 automatically enters standby mode. The power consumption in standby mode is near zero (3.3μW).

Do NOT attempt to power the TITAN using the VBUS 1 or VBUS 2 pins!

VBUS 1 and VBUS 2 are isolated +5V supplies switched under hardware control from VCC_PER.

ALWAYS use the USB client cable provided with the development kit. This cable does not provide power down the cable and avoids reverse powering the TITAN from a USB host when the TITAN has no power on the VCC input on J15 pin 1. Reverse powering the TITAN from the VBUSn pins can make the TITAN operate erratically and may cause serious damage to the TITAN.
